- Q: What are the applications of refractory busway?
- Fire-resisting busway can be applied to power transmission and distribution systems with rated voltage below 690V, rated current is 250-5000A and frequency is 50-60Hz. After years of testing and industrial electrical operation, its electrical resistance, fire resistance, metal structural property have reached the advanced level in China.
- Q: What's the fire endurance of hollow brick?
- This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. This is the maximum limit.
- Q: I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
- the fire endurance of fire window is: class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, Class C window is not less than 0.6 hour. technical requirements: 1, materials and accessories (1) the window frame is made by a certain strength of steel frame or wooden frame which is sufficient to safeguard the integrity and stability. (2) steel frame and mound layer can select galvanized?steel?sheet or stainless steel plate. Its selection standards should be in line with the provisions of Article 5.1. in GB12955 "Steel Fireproof Door General Technical Condition" (3) the selection standards of wood frame and mound layer should be consistent with the provisions of Article 5.1.1. in GB14101 "General Technical Conditions of Wooden Fireproof Door" (4 ) the inner filling material of steel and wood frame should be non-combustible material. (5) fireproofing glass can choose the qualified products in fire resistance test and not affecting the fire windows. light transmittance of glass is not less than 75% of identical layers of ordinary plate glass. ( 6) a sealing material between the frame and the fireproofing glass should use the nonflammable material, it can play the role of fireproofing and smoke insulation in the fire disaster. I hope I can help you
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q: What is neutral refractory? Can refractory suppliers tell the main components of it?
- // Baike? Url x3d CQ3i6_yUCWUMgk3aaRGGLURNtvKPl5IdZpj35Yvommk7Nyif0IJD-SkdIW29GCHwLpb9cT9Ii25GLcEJg-ZHcq "target x3d" _blank "x26gt; http://baike.baidu.baidu.
- Q: what textures of furnace refractories are good?
- Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.
- Q: Who knows about the B-level fireproof insulation materials?
- Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
- Q: What is the the best ratio of mortar in refractory cement?
- The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
